1. The right answer is - Hypothalamus (manufactured by the hypothalamus, stored in the pituitary gland).
Vasopressin, or antidiuretic hormone, is a peptide hormone synthesized by the supraoptic and paraventricular nuclei of the hypothalamus, and released by the posterior pituitary gland (neurohypophysis).
It mainly has an anti-diuretic role in the kidney, where it causes a reabsorption of water via an action on the distal segment of the nephron during a dehydration body. Its gene is AVP located on human chromosome 20.
2. The right answer is - Increased Secretion of Vasopressin To Maintain Less Loss Of Water.
Vasopressin has an antidiuretic action: it decreases the volume of urine by increasing the water permeability of the collecting tube. It binds to the V2 receptor, which is coupled to a Gα protein, which activates a signaling cascade through the PKA. This causes the synthesis of aquaporin 2 (transmembrane pore) as well as its translocation to the apical / urinary membrane.

❖ Before mitosis and meiosis occur, DNA replication has to occur. DNA replication is when another copy is made of the DNA and in mitosis and meiosis, you need the replicated DNA for the sister chromatids.

my guess is B. I am probably wrong
Hydrophonic plants are plants that is living in the lands,
and obviously the aquatic plants that are typically used to style aquariums.
However, the bubbles you can perceive in an aquatic plant can perhaps be a source
of oxygen which is recognized as one of the products of plants as well as human respiration. The bubbles
are oxygen and are created from the thylakoid membrane in the chloroplast over photosynthesis.
